While biotechnologies offer eco-friendly solutions for eliminating air contaminants, there is a scarcity of research examining the impacts of microbial purification of air pollutants on the structure and function of air microbial communities. In this study, we explored a Lactobacillus paracasei B1 (LAB) agent for removing ammoniacal odour. The impacts of LAB on air bacterial community were revealed.

Green electrospinning for the production of freshness-indicating labels, employing entirely natural biopolymers and pigments, holds significance in the development of intelligent food packaging. This study aimed to prepare zein (Z) fibrous film (FF) incorporated with varying concentrations of anthocyanin (A; 0-0.5 %) through green electrospinning.

The objective of this study was to compare fermentation profile and microbial diversity from rumen samples collected using a rumen cannula (RC) or stomach tube (ST) in lactating dairy cows. Three ruminally cannulated lactating dairy cows were used in a 3 × 3 Latin square design. The experimental period was 28 d and rumen fluid was collected 4 h after feeding on d 22 and 26 of each experimental period.

Optical characterization of dissolved organic carbon (DOC) freshly collected from the circumneutral "white water" of the Rio Solimoes revealed that it had lower aromaticity, lower molecular weight, and a greater autochthonous content than DOC from the acidic "black water" of the Rio Negro. The tambaqui (Colossoma macropomum), a characid member of the Serrasalmidae, is a model neotropical fish that migrates annually between the two rivers. We analysed ionoregulatory responses of the tambaqui over 24 h in ion-poor water at pH 7.

Observational studies of marine aerosols are essential for understanding the global aerosol budget and its environmental impacts. This study presents simultaneous in-situ measurements of major ionic components (Cl, NO, SO, NH, K, Ca, Na, and Mg) in aerosols and gaseous species (HCl, HNO, HONO, SO, and NH) over the North Pacific Ocean from July 4 to 15 and September 19 to October 3, 2022. Using high temporal resolution instruments aboard the Republic of Korea's icebreaker research vessel Araon, this study aimed to (1) report the spatial and temporal distributions of aerosols and gaseous species, (2) estimate the source contributions of continental anthropogenic pollutants, and (3) assess the influence of aerosol chemical composition and gaseous species on aerosol acidity and water content.
